Can you run a ping artifacts.elastic.co and show the output?

Can you also run host artifacts.elastic.co or nslookup artifacts.elastic.co and paste the output? It looks as if your DNS resolution is not configured correctly.

hi Mark Walkom,

very sorry for my late response. i was actually out of station for last 3 days and with very limited internet connectivity :smiley:

here is the response,

/usr/share/elasticsearch$ ping artifacts.elastic.co
ping: unknown host artifacts.elastic.co

looks like a DNS issue... is there any workaround?

Hi Alexander Reelsen

very sorry for my late response. here is the output...

/usr/share/elasticsearch$ host artifacts.elastic.co
;; connection timed out; no servers could be reached
irtizaur@ubuntu:/usr/share/elasticsearch$ nslookup artifacts.elastic.co
;; connection timed out; no servers could be reached

yes, looks like the issue is on the DNS side... any workaround?

From the looks of it, your server is isolated from the wider internet - probably intentionally.

You'll need to do an offline install.
Download the xpack zip file on a machine that has internet access, and then copy it across to your server and install from a file.
